Filmmaker Dan Savage took this picture of a uniquely colored koi found in the ponds of Maruoka Castle, the second oldest standing castle in Japan.

Beyond the unusual blue color overall, the mottled burgundy and indigo effect from the more vividly colored scales on this carp’s back makes it even more attractive to me. I could be wrong, but I would guess this fish would be prized far more than a basic $500 nishikigoi specimen.
